The Performance of Islamic Vs. Conventional Banks: Evidence on the Suitability of the Basel Capital Ratios

This paper examines the effect of various types of bank capital on the profitability and efficiency of conventional and Islamic banks. Our results show that higher quality forms of capital improve the profitability and efficiency for both systems although the results are stronger for conventional banks. The capital effect is more pronounced for large, too-big-to-fail, and highly capitalized banks. The results are robust across various subsamples, alternative profitability and efficiency measures, and different estimation techniques.     

Positive and negative synergies between the CEO's and the corporate board's human and social capital: A study of biotechnology firms

This paper contributes to the corporate governance literature by developing and testing theory regarding positive and negative synergies between the CEO's and the board's human and social capital. Using a sample of 360 biotechnology firms that went public between 1995 and 2010, we demonstrate that accumulated public company board experiences of the CEO and the board have positive synergistic effects on IPO performance whereas the current board appointments have negative effects. While scientific educational backgrounds have positive synergies, industry‐specific experiences produce either positive or counterproductive effects depending on the age and profitability of the firm. Thus, our paper contributes to the corporate governance and human and social capital literatures by describing the costs and benefits of specific types and combinations of CEO and board capital.

Investor Reaction to Inter-corporate Business Contracting: Evidence and Explanation

We examine the stock market reaction to 1227 inter-corporate ordinary business contract announcements reported by Dow Jones between January 1, 1990 and December 31, 2001. Around contract announcement dates, we find statistically significant positive average abnormal returns and abnormal trading volume for contractors, but insignificant positive abnormal returns and negative abnormal volume for contractees. Cross-sectionally, contract announcement period returns are higher for contractors who are small relative to the contract size, have higher return volatility, larger market-to-book ratios and higher profitability. The announcement period returns of contract-awarding firms are not significant and are only marginally related to cross-sectional explanatory factors. The results are consistent with two explanatory stories: contractor quasi-rents induced by the winner's curse and information signalling about contractor production costs. The results are not consistent with perfect competition, with contracts having positive net present values for both parties, and with a version of incomplete contracting theory.     

Underwriter learning about unfamiliar firms: Evidence from the history of biotech IPOS

This study examines the ability of underwriters to properly value unfamiliar firms prior to issuance. I use a sample of IPOs in biotechnology, a relatively new but thriving industry. The first American biotech IPO was in 1980. Through the end of 2004, almost 500 biotech IPOs have appeared in the public market. I find that biotechnology differs from other industries in the attributes of individual firms valued by the market. In particular, R&D and the quality of human capital (e.g., star scientists on the staff) are much more important for biotech valuations. I find also that underwriters appeared not to appreciate this distinction for early biotech IPOs; in those cases, first-day market returns were predictable by firm attributes not used by underwriters to establish IPO issue prices. I also find that underwriters have learned over time, albeit slowly. Over the 20+ years of biotech history, IPO issue prices have become more dependent on firm attributes unique to biotechs while first-day market returns have become less predictable.     

Does Disclosure Regulation Work? Evidence from International IPO Markets*

This study examines whether IPO disclosure requirements mandated by countries’ securities laws are associated with variation in IPO underpricing in international IPO markets. Our empirical analysis uses a unique sample of 6,025 IPOs from 34 countries over the period from 1995 to 2002. We show for the first time that the stringency of disclosure requirements for IPO prospectuses is negatively associated with the extent of IPO underpricing, after controlling for various country‐ and firm‐level determinants of underpricing. Moreover, we find that the disclosure effect on IPO underpricing is moderated by the extent of a country’s capital market integration. Taken together, our findings are consistent with the view that increased disclosure regulation appears to reduce IPO underpricing and hence the cost of equity, and that institutional factors such as capital market integration play an important role in understanding the economic consequences of disclosure regulation in international IPO markets.     

Market fragility and international market crashes

We extend the Pukthuanthong and Roll (2009) measure of integration to provide an estimate of systemic risk within international equity markets. Our measure indicates an increasing likelihood of market crashes. The conditional probability of market crashes increases substantially following increases of our risk measure. High levels of our risk measure indicate the probability of a global crash is greater than the probability of a local crash. That is, conditional on high levels of systemic risk, the probability of a severe crash across multiple markets is larger than the probability of a crash within a smaller number of markets.     

Insider trading in rumored takeover targets

We examine insider trading surrounding takeover rumors in a sample of 1,642 publicly traded US firms. Using difference-in-differences regressions, we find that insider net purchases increase within the year prior to the first publication of a takeover rumor, particularly when rumor articles are either accurate (lead to a takeover announcement) or informative (provide substantial justification for the rumor's publication). Moreover, we find abnormal insider trading to be a significant predictor of takeover announcements occurring within the following year. Finally, passive net purchasing (i.e., selling less rather than buying more) is more pronounced among managing insiders than among non-managing insiders.     

International diversification with frontier markets

We provide an analysis of frontier market equities with respect to world market integration and diversification. Principal component results reveal that frontier markets exhibit low levels of integration. In contrast with developed and emerging markets, frontier markets offer no indication of increasing integration through time. Furthermore, individual frontier market countries do not exhibit consistent rates of changing integration. Structural break tests identify breakpoints in integration, as well as integration dynamics across countries. We show that frontier markets have low integration with the world market and thereby offer significant diversification benefits.     

Global market integration: An alternative measure and its application

Global markets seem to be increasingly integrated but there is no well-accepted measure of integration. We show that the correlation across markets is a poor measure; perfectly integrated markets can exhibit weak correlation. We derive a new integration measure based on the explanatory power of a multi-factor model and use it empirically to investigate recent trends in global integration. For most countries, there has been a marked increase in measured integration over the past three decades, but this is not indicated by correlations among country indexes.
